Stay on trails: taking shortcuts causes trail erosion and is dangerous. In hydrothermal areas, stepping on thin crust may plunge you into boiling water.

Wildlife at Yellowstone in September

Around the second week of September, you’ll begin to hear the high pitched bugle of bull elk signaling the elk rut! The town of Mammoth is a terrific place to watch the male elk exert their dominance.

Bears return to the lower elevations looking for berries and bull bison or elk that perished during the rut. Migratory hawks and eagles begin to travel south and west for the winter.

We’ve put together this resource of the best time to visit yellowstone for wildlife in case you want to see a specific animal in the park.

Remember the parameters to keep you and the animals safe!

Never approach animals. The animals in Yellowstone are wild and unpredictable, no matter how calm they appear to be.
The safest (and often best) view of wildlife is from inside a car. Always stay at least 100 yards (91 m) away from bears and wolves, and at least 25 yards (23 m) away from all other animals, including bison and elk.
Never feed wildlife. Animals that become dependent on human food may become aggressive toward people and have to be killed. Keep all food, garbage, or other smelly items packed away when not in use.
Never park in the road or block traffic. Use pullouts to watch wildlife and let other cars pass. Stay with your vehicle if you encounter a wildlife jam.

Yellowstone Photography in September

We recommend you have your camera ready to go because the wildlife you may see as you drive through the park won’t wait for you to find the camera in your car.

In September you’ll also want to photograph the geysers, hot pools, waterfalls and rivers. Here are some tips for taking pictures at Yellowstone.
